How effective are interventions at enhancing preschool children's empathy? A meta-analytic review

Empathy, defined as sharing and understanding others’ emotional experiences, is key to the formation of social groups and plays an important role in children’s social development. While enhancing this skill in early education has been a focus in the field, whether trainings emplo...

Basin-scale organization of groundwater and surface water during the monsoon season: Hydrochemical and isotopic insights from the Brahmaputra River Basin, Northeast India

Study region The Indian sector of the Brahmaputra River Basin (BRB). Study focus We co-evaluated groundwater (GW) and river water (RW) across the Indian BRB using a synoptic monsoon-season survey (July 2022; n = 83; 36 GW, 47 RW). Hydrochemistry, stable isotopes (δ²H, δ¹⁸O), wate...

Linewidth narrowing in silver-coated fiber surface plasmon resonance sensors through waveguide-structure-dependent modal regulation

Broad resonance dips limit the spectral resolution and figure of merit (FOM) of wavelength-interrogated fiber surface plasmon resonance (SPR) sensors. Here, silver-coated no-core fiber (NCF), multimode fiber (MMF), and hollow-core fiber (HCF) probes were compared under matched se...

Physics-consistent alignment and discrepancy learning for multi-fidelity prediction of train collision load

Train collision accidents may lead to severe casualties and substantial property losses, making crashworthiness analysis essential for improving train passive safety. However, the high computational cost of high-fidelity numerical simulations limits their direct application to la...

Distribution of relaxation time analysis for stage-resolved flexural damage sensing in carbon black-modified ultra-high-performance concrete

Self-sensing cement composites convert mechanical deformation and cracking into measurable electrical responses. However, the conductive-network evolution underlying resistance variation and their ability to track loading-induced damage remain insufficiently understood. Here, we...

Boosting ambient-pressure CO2 hydrogenation to methanol: Lattice Mo doping modulates electronic structure of In2O3

Precisely modulating the local electronic structure of oxygen vacancies is key to improving the inferior catalytic activity of In 2 O 3 toward CO 2 hydrogenation to methanol under atmospheric pressure. Herein, we demonstrate that lattice-incorporated Mo, rather than surface modif...

Increasing absolute prey density within a mimicry complex protects aposematic models and their Batesian mimics

Abstract Batesian mimicry is a defensive adaptation where predators learn to avoid aposematic prey and generalize their warning signals to phenotypically similar mimics. The phenotypic accuracy needed for mimics to benefit from this adaptation depends on the relative densities of...

Physics-inspired neural network prediction of high-Q near-field spectra for roughness-engineered plasmonic metasurfaces

In plasmonic metasurfaces, structural roughness is conventionally regarded as a source of parasitic loss and degradation of surface lattice resonances (SLRs). Here, we demonstrate that roughness can be strategically harnessed as an active design degree of freedom, orthogonal to c...

A compact piezoelectric inertial bone-conduction transducer with broadband vibration response

Externally worn bone-conduction devices suffer from high-frequency vibration attenuation induced by the low-pass filtering effect of the skin-soft-tissue layer during transcutaneous vibration transmission. Meanwhile, conventional electromagnetic transducers struggle to balance br...

A systematic review of energy and thermo-visual performance of photovoltaic glazing in office buildings

The integration of smart photovoltaic (PV) glazing into building envelopes offers a critical solution for balancing energy efficiency with occupant comfort, particularly in hot climates where cooling loads and solar glare are dominant challenges. This systematic review synthesize...

Soluble N-terminal EphA2 fragment as a diagnostic biomarker and functional mediator of tumor progression in triple-negative breast cancer

Triple-negative breast cancer (TNBC) lacks reliable biomarkers for early detection and remains a highly aggressive disease. Ephrin type-A receptor 2 (EphA2), a receptor tyrosine kinase frequently overexpressed in advanced cancers, undergoes MMP14-mediated cleavage that releases s...

Synthesis study of formation bioavtur-type hydrocarbons from waste cooking oil-derived biodiesel (FAME) through sub-micron bubbles ozonolysis reactor

The fossil fuel crisis has encouraged the development of biofuels as a renewable alternative fuel for the aviation sector. This study examines the ozonolysis method using a sub-micron bubble reactor to convert waste cooking oil-derived biodiesel (fatty acid methyl esters, FAME) i...

Yield comparison of tillage and irrigation regimes in a rice–wheat production system in the Indian mid-Himalaya

Background Meeting the increasing food demand under changing land use, constrained water resources, and rising climatic variability requires resource-conserving management of the rice–wheat (R-W) system in the Indian mid-Himalayas. Zero tillage (ZT) and improved irrigation schedu...

The effect of alloying, hot forging, and heat treatment on the microstructure, mechanical properties, and oxidation resistance of O-Ti2AlNb based intermetallic alloys

In the present work, novel physicochemical approaches are proposed for the design of alloys based on the O(Ti 2 AlNb) phase by balancing Al and Nb equivalents to maintain a two-phase O+β/B2 composition, and alloying with elements having high melting points and/or larger atomic ra...

Design and Flight Validation of Monocular-vision-based Relative Altitude Estimation for Precision Landing of Lightweight Aerial Vehicles

Monocular-vision-based precision landing is promising for small unmanned aerial vehicles operating under strict payload constraints. However, detection noise and image disturbances can degrade altitude estimation accuracy and destabilize terminal landing performance. This study p...

From quality to value: linking product and system perspectives in the plastic packaging ecosystem

This study investigates value in the plastic packaging ecosystem. Previously, we identified the quality perceptions of technical actors, such as polymer producers, converters and recyclers. Using semi-structured interviews, we now extend this by focusing on value for broader ecos...
